Vaginal microbiota in healthy pregnant women and prenatal screening of group B streptococci (GBS).
The microbiota of the lower female genital tract was evaluated from vaginal swabs obtained from 623 healthy pregnant women at gestation periods of 35-40 weeks. Isolated and identified microorganisms were expressed as percentages of total samples. As expected, lactobacilli made up the dominant vaginal microbiota (70%). Enterobacteriaceae, mainly Escherichia coli, Klebsiella spp. and Proteus, wer...
متن کاملAntibiotic resistance patterns of group B streptococci in pregnant women.
This study examined the antibiotic resistance patterns of group B streptococci (GBS) isolated from gravid women. A total of 156 vaginal and cervical isolates of GBS were examined for resistance to penicillin, ampicillin, clindamycin, cefoxitin, gentamicin, and erythromicin. No resistance to penicillin or ampicillin was found, nor was penicillinase production demonstrated. A high level of resist...
متن کاملOxygen-stable Hemolysins of Group a Streptococci
The relationship of the streptococcal hemolysin which is recognized on incubation of RBC with streptococcal cells (cell-bound hemolysin, CBH), to RNA hemolysin, a representative of oxygen-stable hemolysin (streptolysin S) has been studied. A number of similarities have been found in the conditions for optimal production of each of these hemolysins, a requirement for cysteine, Mg(++), and glucos...
متن کاملGroup B streptococci--gastrointestinal organisms?
Matched perianal swabs, rectal swabs, and faecal samples from a group of male homosexual patients attending a clinic for sexually transmitted disease were examined for the presence of group B streptococci (GBS). GBS recovery rates were as follows: perianal skin 31/115 (27%), rectal mucosa 18/72 (25%) and faeces 7/115 (6%). The recovery of GBS from faeces was similar to that obtained from faecal...
متن کاملKilling kinetics of group B streptococci for penicillin in combination with gentamicin
In vitro synergism and killing kinetics studies of penicillin in combination with gentamicin were performed with group B streptococci recently isolated in Belgium. The expected accelerated killing was not observed when compared with penicillin alone. D 2005 Elsevier B.V. All rights reserved.
